WHOOP expands Advanced Labs with a blood panel built for women’s physiology

Most standard blood panels interpret women’s results against static reference ranges that don’t account for changes in menstrual changes. And when it comes to hormones like progesterone being wildly different at day 7 versus day 2, that’s a real problem. WHOOP is trying to fix that gap with a Women’s Health Specialized Blood Biomarker Panel, launching in April as part of its Advanced Labs testing lineup.

What’s in the panel

The panel covers 11 female-specific biomarkers tied to cycle regulation, hormonal transitions (including perimenopause), thyroid function, nutrient status, and bone health. The full list: Anti-Müllerian Hormone (AMH), Progesterone, Prolactin, Thyroid Peroxidase Antibodies (TPOAb), Free T4, Free T3, Leptin, Vitamin B12, Folate, Magnesium, and Phosphate.

The more interesting part is how WHOOP reads the results. When a member completes a blood draw, the app automatically applies reference ranges calibrated to her current cycle phase. So a result, biomarkers that would get flagged as “out of range” on a generic panel might actually be optimal for that point in the cycle. Results are categorized as optimal, sufficient, or out of range, and layered on top of continuous data from the wearable. That combination of bloodwork and real-time physiology data is what separates this from ordering a panel through your doctor and getting back numbers with no context.

Hormonal Symptom Insights and Predictions

Alongside the new panel, WHOOP is rolling out a Hormonal Symptom Insights and Predictions update within its existing Cycle Insights feature. Rather than just logging symptoms after the fact, the update builds a personalized model that adapts over time based on a member’s physiological patterns. That includes:

• A dynamic date window for the next period
• Tracked trends in cycle length, period length, and variability — with flags for irregular patterns
• Anticipated symptom timing based on individual historical data

The goal is to give members enough lead time to adjust training, recovery, and daily routines before symptoms hit, not after.
“What makes this powerful isn’t any single data point, it’s how the system comes together,” said Emily Capodillupo, Senior Vice President of Research, Algorithms, and Data at WHOOP. “Women don’t experience their physiology in silos. Hormones influence sleep, sleep affects recovery, and recovery shapes training response. By modeling these interactions over time, across continuous biometrics, lab data, and behavior, we can deliver guidance that reflects the full system, not just a snapshot.”

WHOOP is also working with Clue, a leader in menstrual and reproductive health, as part of a broader push to close the data gap in women’s health research.
